People do some strange things when they have time to kill. Making the Death Star out of a cantaloupe or watermelon is one of the cooler (but still ever so slightly strange) things.

You were told as a child to never play with your food but, to be frank, sometimes when a cool idea suddenly hits, the temptation is just too strong. So, you take a watermelon. You just can't help noticing that it already kinda looks like the Death Star. It doesn't look quite right on a plate, though. Time to experiment.
